I The present invention relates to a canule for the teats of cows, which has such a softness and flexbility that it will notfinjure the texture of the udder. i i g, It is therefore easier tovintro'duce it without great pain to the animal and is, later on, less troublesome in milking than a normal 'canule of sttf material as it can bend with the teat. i

In the accompanying drawing a form ofV such a` canule is shown by way of example.

The drawing shows a longitudinal section' through a cowteat canule.V The numeral l' ndicates the canule itself, which ishollow i liand made of a soft flexible material, for example caoutchouc or thelike.V The canule is closed at'the top andfhas at the upper end f v two lorniore holes 2, through which the milk* can enter intoflthe canule. The latter has bepushed. too far up. Furthermore it has ata suitable distance from its lower end an en be pushed through the canule, the holes 2 in i Beforethe oanule'shall be used, it is placed teats of oows,fmade of a soft, elastic material, 5

having near its lower end an ,'enlargement,-

adapted tohbe compressed andagain expand T, during the milking thereby assisting the pasi sage of the milk through the teat. I v r In testimony whereof I aflix my signature.

i JOHANNES ermlxnnvD-nYenl i low4 a collar 3 which shall prevent its being y er) the latter are preferably arranged at the sides of the same. After the eanule has been introduced, the rod is withdrawn. Y By, such mode of introduction it is atv tained that the canule may be made, as aforesaid, of a very soft material,

A canule according to the present invention may be made of any other suitable form f .I than here described. The enlargem'ent 4: which serves to hold the canule in position VLie may, :forexample, be made with grooves and the like for better offering resistance agalnstj' its being shifted.

. 'If the canule has two holes, as shown, these maybe arr'anged, for example, diametrally i to each other and at different' levels, so 'as not f i to weaken the wall of the canule too much at the respective place, not more than'necessary. I Y

I claim:
